Six sediment samples weighing between 224–735 g were collected in June of 2016 from Cayo Nuevo reef, located at the Campeche Bank, southern Gulf of Mexico. Samples were collected by SCUBA diving, from were two stations at depths of 7.6 and 18.2 m. Sediment was sieved and molluscs (adults and micromolluscs ≤ 10 mm) were sorted, examined, and identif...

... Gaps in our knowledge of historical biotic changes often stem from a paucity of information about species geographic distributions, community species richness and evenness, community structure, ecological interactions, and factors that caused past biotic shifts. Nevertheless, recent marine mollusc inventories have begun to expand our knowledge of the biota and environmental conditions in some regions, such as the Gulf of Mexico Reguero, 2004, 2007;Mikkelsen and Bieler, 2008;Moretzsohn et al., 2009;Ortigosa et al., 2018;Rosenberg et al., 2009;Turgeon et al., 2009;Vokes and Vokes, 1983;Wingard andStackhouse, 2020a, 2020b;Wingard and Surge, 2017), and in Río Lagartos coastal lagoon (Gonzalez et al., 1991;Suárez-Mozo et al., 2023).

Antecedentes:
El Parque Nacional Archipiélago Espíritu Santo es reconocido por su elevada biodiversidad. Los estudios realizados sobre los moluscos de fondos blandos son inventarios faunísticos, y se conoce poco sobre la variación de su estructura comunitaria.
Objetivo:
Conocer la composición y la variación espacial en la estructura de los ensambles de moluscos de fondos blandos de este archipiélago y describir la posible relación con el tipo de sustrato.
Métodos:
En la zona infralitoral se distribuyeron 66 sitios de muestreo en nueve localidades. La colecta de moluscos se realizó mediante buceo autónomo utilizando un marco metálico de 1m² y para el análisis de la textura del sedimento un nucleador. Se estimaron los indicadores estructurales de abundancia (N), riqueza de especies (S) y los índices de diversidad de Shannon-Wiener (H´) y de Equidad de Pielou (J´).
Resultados:
El sustrato de arena de grano medio presentó la mayor contribución. Se cuantificaron 23 743 organismos, registrados en 102 especies distribuidas en tres clases, 17 órdenes, 39 familias y 70 géneros. Los bivalvos estuvieron representados por 48 especies, 39 géneros, 17 familias y nueve órdenes. Los gastrópodos por 52 especies, 30 géneros, 21 familias y siete órdenes y los escafópodos por una especie. Se encontraron diferencias significativas entre las localidades para la riqueza de especies y diversidad, pero no para equidad.
Conclusiones:
Se observaron variaciones espaciales en la estructura de los ensambles de moluscos en el archipiélago, las cuales pudieron ser debidas al efecto combinado de la textura del sedimento y a la presencia de mangles en algunas localidades.
SSP (simulation‐based sampling protocol) is an R package that uses simulations of ecological data and dissimilarity‐based multivariate standard error (MultSE) as an estimator of precision to evaluate the adequacy of different sampling efforts for studies that will test hypothesis using permutational multivariate analysis of variance. The procedure consists in simulating several extensive data matrixes that mimic some of the relevant ecological features of the community of interest using a pilot data set. For each simulated data, several sampling efforts are repeatedly executed and MultSE calculated. The mean value, 0.025 and 0.975 quantiles of MultSE for each sampling effort across all simulated data are then estimated and standardized regarding the lowest sampling effort. The optimal sampling effort is identified as that in which the increase in sampling effort does not improve the highest MultSE beyond a threshold value (e.g. 2.5%). The performance of SSP was validated using real data. In all three cases, the simulated data mimicked the real data and allowed to evaluate the relationship MultSE – n beyond the sampling size of the pilot studies. SSP can be used to estimate sample size in a wide variety of situations, ranging from simple (e.g. single site) to more complex (e.g. several sites for different habitats) experimental designs. The latter constitutes an important advantage in the context of multi‐scale studies in ecology. An online version of SSP is available for users without an R background.
The genus Lodderena Iredale, 1924 has been classified in the Skeneidae by most recent authors. However, this family, originally characterized by their minute size, lack of nacre in the teleoconch and a rhipidoglossate radula, is currently considered to be polyphyletic assemblage, and preliminary molecular systematic data suggest exclusion of Lodderena from Skeneidae. In order to shed light on the systematic position of this genus, we provide a detailed description of the anatomy and histology of the type species, Lodderena minima (Tenison-Woods, 1878), and of L. ornata (Olsson & McGinty, 1958). The anatomical data confirm the vetigastropod-trochoid nature of Lodderena but exclude the genus from Skeneidae. Skeneidae are mainly characterized by a propodial penis, a hermaphroditic condition with separated testis and ovary, and a large receptaculum in the mantle roof. In contrast, Lodderena species lack both a copulatory organ and receptaculum, and have a true ovotestis. We also provide a critical review of nominal species in the genus. Based on molecular and morphological evidence, we exclude Lodderena from Skeneidae, instead treating it as a genus incertae sedis within Trochoidea. We discuss the implications of small size for functional morphology and reproduction.
